Flash Marriage with My Stoic Boss: Cold in Public, Passionate in Private Blurb Nora Ward has two rules for marriage: low-maintenance and zero drama. As a chief cardiology resident running on coffee and four hours of sleep, she doesn't have time for romance. A blind date gone wrong lands her at the wrong table with the right man — Adrian Cross, a cold, brutally efficient cardiothoracic surgeon just back from the US. They size each other up over iced coffee. Same schedule. Same pragmatism. Same need for a spouse who stays out of the way. Thirty minutes later, they leave the courthouse with a marriage certificate and no intention of ever seeing each other outside a hospital. Problem is — they work at the same hospital. And Adrian Cross just happens to be her department's newly appointed deputy chair. Now she has to face him at morning rounds, pretend he's a stranger, and ignore the way his voice drops an octave when he says "Dr. Ward" — professional, distant, infuriating. Rules are easy to make. Harder to keep when your stoic husband corners you in the on-call room after midnight and proves he's anything but cold. This is why you don't flash-marry your boss.
